30 purification unit 100 so that fitters 112 that are Inserted into positions or other
components such as control panel and processor can be electrically
connected to the mains and operated through contacts 124. It is optional to
provide within purification unit 100 environmental purification and enrichment
components, some of which require voltage for operation and some do not In

WO 2004/108248 PCT/TL2004/000484
10
addition, a motor of air circulating fan 118 is also provided adapted to force air
to pass through purification unit 100 and through the purification and
enrichment elements so as to filter and enrich the air in the space to be
purified. It should be noted that any fitter operated in any voltage can be
5 provided in any position or any order other than the order indicated in the
example and it will be successfully operated.
Generally, there are filters or air enrichment elements that require
electricity in order to work such as UV lamp, electrostatic filter, mosquito killer,
or other and there are also filters "or air enrichment elements that do not
10 require electricity and perform only due to the air that passes through them
such as scent box, active coal, or coarse filters from different types. The types
of filters and environmental enrichment elements that will be used in a specific
purification unit depend of the type of air in the space to be purified and the
specific requirements. One of the scopes of the present invention is ihe ability
15 to provide a purification system in which the type of filters can be determined
or altered in a simple manner and the arrangement of the filters or air
enrichment elements in the positions is fully modular so that any position
(grooves 20 in Figure 1 or slots 72 in Figure4) is adapted to receive any filter
or enrichment element without consideration of the voltage it receives. Any
20 type of fitter, whether electrically operated or not, can be inserted into the
positions. This is also fully modular,
As mentioned herein before, preferably three modular voltage plugs 104
are provided in direction through which enhancements units may be
connected. In Figure 5a, an financing unit that comprises modular voltage

between purification units 202 and the control panel through corresponding
data plugs and voltage guide line 205. The voltage plugs are connected in a
15 mail-female manner. The user can easily detach a purification unit so as to
change the air improvers within the purification units, maintenance or for any
other purpose. In a similar mannar, one can modify the filters if the conditions
in the space are changed as well as add additional enhancing units if there is
a need. As can be seen in Figure 6a, floor housings are connected with a fast
20 connector 222, Additional housings can be connected with additional
purification units that are plugged' to the system In an easy manner. An
integral grille 203 is provided in the outlets and the inlets of the units (basic or

controller and a control panel 502 and. two enhancing units 504 on both sides
of the purification unit. The units are adjacent to each other on one side so as
20 to establish an arrangement that can be suspended of the ceiling or hanged
on a wall. Figure 7c illustrates a triangular arrangement of the same three-
units system. Figure 76 illustrates a sis units purification system 600
comprising two units each comprising a main purification unit and two
enhancing units. In this case, each three units system can be operated
25 independently; however this arrangement can be also built of six units
comprising a purification unit connected to five enhancing units.
Figures 7e and 7f illustrates a purification system arranged of four units
in a row 700 and in a square 800, respectively. Only one purification unit 702
and 802, respectively, is provided with controller and controlling panel 704
30 and 304, respectively. Each unit is provided with a door 706 in "the bottom of

25 with filters 964 and grilled port 966.
Due to positioning limitations, the enhancing unit has to be connected in.
a step-wise positioning relative to the basic unit. For that reason, a diverting
unit 968 is provided to divert the air coming from basic unit 952 into the
connected enhancing unit Voltage is transferred from controller 958 through
30 electricity channels that are provided all through the units are provided also in
diverting unit 958. Plugs 970 for transferring voltage through the units are
